Today, We observed the semisolid agar motility test tube, finding out our unknown bacteria was motile, and our environmental bacteria was not. Following this, we performed the hanging drop test for motility using a special concave lens and a lens cover to observe the bacteria swimming! Then we classified our bacteria. Our unknown bacteria, L 25, is red, rod shaped (bacillis) and motile. In the agar slant tube, the unknown was filiform. In the broth tube, it was turbid, having sediment, a ring around the top, and flocculent simultaneously. Our environmental sample, was circular, cream/tan in color, entire and raised. In the broth tube, it had sediment, turbid, and was tan in color. We also studied the reaction of bacteria to antibiotics, finding out Dr. Pathakamuri did not have strep throat because the bacteria did not completely lyse the red blood cells, even though it was killed by bacitracin.
